More Russian SVR Supply-Chain Attacks

October 28, 2021
Ed Gardner 0

Microsoft is reporting that the same attacker that was behind the SolarWinds breach — the Russian SVR, which Microsoft is calling Nobelium — is continuing with similar supply-chain attacks:

Nobelium has been attempting to replicate the approach it has used in past attacks by targeting organizations integral to the global IT supply chain. This time, it is attacking a different part of the supply chain: resellers and other technology service providers that customize, deploy and manage cloud services and other technologies on behalf of their customers. We believe Nobelium ultimately hopes to piggyback on any direct access that resellers may have to their customers’ IT systems and more easily impersonate an organization’s trusted technology partner to gain access to their downstream customers. We began observing this latest campaign in May 2021 and have been notifying impacted partners and customers while also developing new technical assistance and guidance for the reseller community. Since May, we have notified more than 140 resellers and technology service providers that have been targeted by Nobelium. We continue to investigate, but to date we believe as many as 14 of these resellers and service providers have been compromised. Fortunately, we have discovered this campaign during its early stages, and we are sharing these developments to help cloud service resellers, technology providers, and their customers take timely steps to help ensure Nobelium is not more successful…

Problems with Multifactor Authentication

Roger Grimes on why multifactor authentication isn’t a panacea:

The first time I heard of this issue was from a Midwest CEO. His organization had been hit by ransomware to the tune of $10M. Operationally, they were still recovering nearly a year later. And, embarrassingly, it was his most trusted VP who let the attackers in. It turns out that the VP had approved over 10 different push-based messages for logins that he was not involved in. When the VP was asked why he approved logins for logins he was not actually doing, his response was, “They (IT) told me that I needed to click on Approve when the message appeared!”…

Textbook Rental Scam

Here’s a story of someone who, with three compatriots, rented textbooks from Amazon and then sold them instead of returning them. They used gift cards and prepaid credit cards to buy the books, so there was no available balance when Amazon tried to charge them the buyout price for non-returned books. They also used various aliases and other tricks to bypass Amazon’s fifteen-book limit. In all, they stole 14,000 textbooks worth over $1.5 million.

The article doesn’t link to the indictment, so I don’t know how they were discovered.

FBI Had the REvil Decryption Key

The Washington Post reports that the FBI had a decryption key for the REvil ransomware, but didn’t pass it along to victims because it would have disrupted an ongoing operation.

The key was obtained through access to the servers of the Russia-based criminal gang behind the July attack. Deploying it immediately could have helped the victims, including schools and hospitals, avoid what analysts estimate was millions of dollars in recovery costs.

But the FBI held on to the key, with the agreement of other agencies, in part because it was planning to carry out an operation to disrupt the hackers, a group known as REvil, and the bureau did not want to tip them off. Also, a government assessment found the harm was not as severe as initially feared…

Using “Master Faces” to Bypass Face-Recognition Authenticating Systems

Fascinating research: “Generating Master Faces for Dictionary Attacks with a Network-Assisted Latent Space Evolution.”

Abstract: A master face is a face image that passes face-based identity-authentication for a large portion of the population. These faces can be used to impersonate, with a high probability of success, any user, without having access to any user-information. We optimize these faces, by using an evolutionary algorithm in the latent embedding space of the StyleGAN face generator. Multiple evolutionary strategies are compared, and we propose a novel approach that employs a neural network in order to direct the search in the direction of promising samples, without adding fitness evaluations. The results we present demonstrate that it is possible to obtain a high coverage of the population (over 40%) with less than 10 master faces, for three leading deep face recognition systems…

Zoom Lied about End-to-End Encryption

August 5, 2021

The facts aren’t news, but Zoom will pay $85M — to the class-action attorneys, and to users — for lying to users about end-to-end encryption, and for giving user data to Facebook and Google without consent.

The proposed settlement would generally give Zoom users $15 or $25 each and was filed Saturday at US District Court for the Northern District of California. It came nine months after Zoom agreed to security improvements and a “prohibition on privacy and security misrepresentations” in a settlement with the Federal Trade Commission, but the FTC settlement didn’t include compensation for users…
